What is the primary function of posture in the human body?
The primary function of posture is to maintain stability or facilitate movement.
Describe the difference between static and dynamic postures.
Describe the difference between static and dynamic postures.
Static postures are maintained consistently to counteract forces, while dynamic postures adjust continually to changes in movement.
What role do anti-gravity muscles play in maintaining posture?

Study Notes
Posture
- Posture is the body's attitude, either during inactivity or through coordinated muscle action to maintain stability or movement.
- Inactive postures are best for rest or sleep when minimal muscle activity is needed. They support vital functions like breathing and circulation.
- Active postures—static or dynamic—require muscle integration. Static postures maintain stable joints, countering gravity. Dynamic postures adapt to movement.
- Muscle intensity varies based on the posture's type and the person. Anti-gravity muscles are crucial for maintaining an upright position.
Postural Mechanism
- Muscles involved in posture, both static and dynamic, vary in intensity and distribution according to the posture and the individual.
- Muscle groups necessary for upright posture work against gravity.
Principles of Exercise Therapy
- Anti-gravity muscles are those crucial for maintaining upright posture. Their action typically involves a form of extension.
- The structure of anti-gravity muscles (multi-pennate and a wide shape) facilitates potent action.
